T0 all whom 'it may concern.'

Be it known that I, FRANKLIN L. LANE,-

the proper adjustment of the parts of such a machine to secure the planing of a board of the desired thickness, whether one or more surfaces thereof are being operated upon. One of its leading objects is to secure a quick but accurate adjustment of the parts of the mechanism and obtain the planed or finished board of the required thickness without measurement by means of rules, scales, or similar graduated instrumentalities. Simplicity in structure, economy in manufacture, ease and certainty of opera.- tion, rapidity of manipulation, eXactness of results, and other desirable objects, are attained in appliances embodying the features of the present invention.

In order that those skilled in this art may have a full and complete understanding of the invention'both from its structural and functional standpoints, I have illustrated a preferred embodiment of the same in the accompanying drawing forming a part 0f this specilication and throughout the views of which like reference characters refer to the same parts.

made to' show the details of the planing mechanism, since an understanding of the invention may be had from the more or less diagrammatic illustration presented. The

machine has the usual upper and lower sectional fced-rollers 11 and 12 and the upper planer cylinder 13 equipped with the customary planing knives. If preferred, the machine may be a double surfacer employing also the lower, companion, planer-cylinder 14. Associated with these is the usual vertically-adjustable bed 15 which can be moved up and down byany suitable or customary means, screws 16 for this purpose being shown more or less diagrammatically and fragmentarily. i

At one side of the bed or platen a curved or otherY suitablyshaped bracket 17, by means of screws 18, 18, is fastened to or rigid with the support or `mounting for the upper feed-rollers and the corresponding planercylinder, and to this bracket a long bar 19 is pivoted or fulcrumed at 20, the other end of such bar being accommodated and guided in a slotted bracket 21 fastened to the same support by screws 22 on the opposite side of the bed. It will be clear, therefore, that the bar transversely overlies the bed. The slot 23 of the bracket has an open top so that the bar may be swung up and down a limited amount, the lower end of the slot ordinarily acting as a support for such end of the bar and as a stop to limit or restrict the downward swinging of the b ar on its fulcrum, as shown in dotted lines in Fig.1.

Relatively near to the fulcrumed end of Y the bar, it is equipped with a block 30 having a threaded stem or shankv31 extended through a hole in the bar, such shank holding the block against the face of the bar by means of its two nuts 32, 32, located on the opposite side of the bar. This construction constitutes a pivotal or oscillatory mounting for the block on the bar, but there is sufficient friction between the parts to prevent turning of the lblock except under intended manual action. The block has a threaded hole down through it receiving an adjustment or vgage screw 33 with a knurled head 34 and a lock-nut 35. Adjacent to the block the bar has a projecting pin 36 vagainst which the block may bear either in its operative upright position shown in full lines in Fig. 1, or in its inoperative inclined relation as indicated in dotted lines in the same figure. Such adjustable gage screw is intended to be used in association with various sizeblocks of known graduated .thicknesses which, of course, require no measurement, one of such blocks being shown in Figs. l and 3.

Assuming that it is desired to adjust the bed of the machine so as to plane a board to a predetermined thickness, the screw .and its companion block are swung from the inclined dotted-line position of Fig. l to vertical position, the bar at this time resting on the bottom of the slot of bracket 21.

Then a size-block, preferably of metal, of

the same thickness asthe desired finishedl board, is placed on the bed l5 beneath the screw, whereupon the bed is fedv or adjusted =upw,ardly until such rising size-block resting on fthe bed, by engagement with Y the lower end ofthe screw, raises the latter and the bar until-the top edge of such bar is in .registerfwith theitop surface'ofbracket 2l ig. 2). -Nowthe screw is swung into inactive diagonal position, the size-block re- -nioved,fan,d the bar permitted to drop to the bottom of the slotted bracket. The machine is new ready to plane a boardgto the required thickness, thejgage-screw, of course, lhaving beengmoved` out .of -position sufficiently so as netto interfereiwith this action. When a single upper v,planing cylinder only is used, itffwillfbeunderstood that when thev screw is 30,11pright and thetop surface of the bar is Kin-alinernent, or register withY the corresponding faceof 'the slotted bracket, the lower -endof-the screw will be in registerV with thelowermostpalt of the planing cylinder l,or one of its knives 4when in its lowermost position. Whem however, the machine-has .agpairofxplaning cylinders for double sur- -facingfwhereasthe lower end of the-gage serewr may not bein exa-ct register with the 40 `knivesfof theupper cylinder when kin their duction ofa'double surfaced board of the required fthickness.

Either in la; single ..surfacer or .double-` surfacer, iif Athe knives have beenY ground or adjusted, fin order to compensate for this action ,init-he screw, itv `is ymerely necessary .to-"run sa eboardathrough the machine', then vplacef-itcupointhe;b ed, which has not inthe meantimesbeen disturbed, and turn the Ascrew tdow-nfnntilfi-ts lower end, by engaging'the ^top5surfaceeof the board, causes the `bar to rise untilitsffedge and that of the slotted zlbracketarefinwregister. Then the lock or elampingtnutfofithe screw is tightened, land therboardcis iremoved, whereupon we may oizproeee'dto` use-.the appliance in the usual `manner.

'Iorthosee skilled? in this art it will be obvviousf .thatthe invention' is not limited and restricte'dnto.the yprecise/and exact features eoffconstnuction .presented because these may Yproper position.

be modiied in many minor details without departure from the substance of the invention and without the sacrifice of any of its substantial benefits and advantages.

In some cases the slotted bracket may be done away with, it'being merely necessary to have some form ofsindexfor the bar to co-act with to indicate when the latter is in It will also be apparent that the appliance could be used in a machine in which the tool or planing Ycylinder is adj usted toward and from the bed insteadA of the bed moved toward and from the tool. Obviously, also, instead of using brackets 17 and'21 separate from-and fastened to the lmounting orsupport for the pressure-rollers andplaner-cylinders, they may be made integral parts of said mounting.

ltwill be appreciated that in the particular embodiment-of the invention set forth in thisapplication, it is desirable to locate the gage screwpand-its block near the pivoted orfulcrum end of the cross-bar, whereby the vadjustments ofthe screw -wi'll bemagnified.; or many'times increased atthe free end ofthe bar,vthus assuring. great accuracy in the use of the appliance. Obviously5 such an arrangement -is not :absolutely essential as the screw may'be located at any Ydesirable vpoint along the length ofthe bar orf-any other suitable and., convenient means fork ob'- vtaining anaccurate adjustment maybe embracket adapted to Vbetfastened' to the mounting for the tool, afibarpivoted near one end to lsaid #bracket and adapted toroverlie the bed of theemachine,v yauslottedA guide-bracket adapted to be secured to s aidtoolmounting and co-act `with the. opposite endaportion of said bar, a lblock pivoted on said `l'bar and varran ed'tobe swun` into o ,'erativerand ing operative lposition, a stop-'pin `iiwithwhich fsaid block is. adapted to coperate, aygaggescrew adjustable in said block towardand from the machine-bed, and vmeans iito-l lock said fgage-screw Vin .adjusted position, -substantially as described.
